For abstractive summarization, we propose a new fine-tuning schedule which adopts different optimizers for the encoder and the decoder as a means of alleviating the mismatch between the two (the former is pretrained while the latter is not). (I don't know for ernie 2) Well your point on finetuned bert vs non finetuned xlnet is interesting. Networks trained with TRP has a low-rank structure in nature, and is approximated with negligible performance loss, thus eliminating fine-tuning after low rank approximation. 65 on ROUGE-L. Source code for claf. View Krishna Chaitanya's profile on LinkedIn, the world's largest professional community. The Transformer is a deep machine learning model introduced in 2017, used primarily in the field of natural language processing (NLP). Trainer (model: allennlp. Abstract: Chinese is a logographic writing system, and the shape of Chinese characters contain rich syntactic and semantic information. For abstractive summarization, we propose a new fine-tuning schedule which adopts different optimizers for the encoder and the decoder as a means of alleviating the mismatch between the two (the former is pretrained while the latter is not). 第一篇把bert用在抽取式摘要上的工作。 bert的架构如下:就是一个transformer编码器 模型输入如下: 这篇文章中使用的结构如下: 其中为了得到每句话的表示,在每句话前面都添加了[cls],来得到每句话的特征[T1, T…. Discharge summary data is designed for downstream tasks training/ fine-tuning. How? Zhang et al. There are among 15 note types in total and Alsentzer et al. Its modular architecture is meant to ease its maintenance and the development and integration of new modules. 这篇将 BERT 用于抽取式文本摘要,主要是选择性抽取文本中的句子作为最后的摘要。这个任务最大的问题是如何获得每个句子向量,然后把向量用于二分类,判断去留。 而 BERT 原模型只能生成单句的句子向量,或者句子对的。. Devoted to machine learning and data science, Projects to Know is an essential weekly newsletter for anyone who wants keeps tabs on the latest research, open source projects and industry news. Our objective here is to fine-tune a pre-trained model and use it for text classification on a new dataset. mt-dnn结合了语言模型和多任务学习,相当于 bert+mtl, 最近在glue一项任务中直接将sota提高了24%。其实本身bert也是包含了多任务学习的思想,这里mt-dnn的话是把任务扩大,使得模型涉及的广度增大。. Fine-tune BERT for Extractive Summarization. In this paper, we aim to improve this task by introducing three auxiliary pre-training tasks that learn to capture the document-level context in a self-supervised. In this tutorial, we will learn how to fine-tune a pre-trained model for a different task than it was originally trained for. The main contributions of BERT are as follows:. 为此我们使用了简单的模型来支持在线训练,并把 Fine-tune 模型的倒数第二层作为特征,增强意图识别的效果。 BERT 的近邻 最近 Google 又携 XLnet 屠榜了,从实验效果看对比 BERT 确实有比较大的提升,我们也在关注中,实验的小手已经蠢蠢欲动了。.

Introduction to PyTorch-Transformers: An Incredible Library for State-of-the-Art NLP (with Python code)- PyTorch-Transformers (formerly known as pytorch-pretrained-bert ) is a library of state-of-the-art pre-trained models for Natural Language Processing (NLP). Just like ELMo, you can use the pre-trained BERT to create contextualized word embeddings. In this paper, we propose a model to learn Chinese word embeddings via three-level composition: (1) a convolutional neural network to extract the intra-character compositionality from the visual shape of a character; (2) a recurrent neural network with self. Our system is the state of the art on the CNN/Dailymail dataset, outperforming the previous best-performed system by 1.
